Application filed September 6, 1916. Serial No. 118,748.

To all whom it may concern:

Be it known that I, DANIEL E. REAGAN, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Attachments for Brickdvlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in attachments for brick machines, and is designed particularly as an improvement on the construction disclosed in U. S. Patent No. 1,100,989 granted to me June 23rd, 1914.

With the patented machine and also with my present improvement I produce rough face brick by plowing up the face and sides of the clay ribbon as the latter issues from the slicker or mouth piece of the die. This plowing throws up from the face, and out from the sides of the ribbon, rows or ridges of clay in strips or particles that are more or less detached from the body of the ribbon. After the plowing, the face and sides of the ribbon are harrowed so as to spread and distribute the strips and particles of clay in an irregular or confusedlayer evenly over the surfaces, and smooth down the edges and ridges of the furrows.- After the harrowing, the roughened surfaces of the ribbon are subjected to pressure to compress and mat the disrupted strips and particles, and cause them to adhere firmly to the body of the ribbon. After the-surfaces of the ribbon have been roughened, it is out into bricks and the latter burned in the usual and well known manner.

The object of the present invention is to simplify the construction so as to provide an attachment that may be attached to any stiff mud brick machine, and carrying the plow, harrow and roller, that will rise and fall with the swell of the ribbon and then produce furrows that are regular as to depth irrespective of any inequalities in the thick ness of the ribbon.

A further object is to provide an improved device for furrowing the brick so that the faces of the latter will show traces of the scoring after the said surfaces have been pressed, or harrowed and pressed, which device is adjustable to produce the roughened faces without leaving traces of the scoring.

A further object is to provide means for the simultaneous adjustmentof all the scoring or furrowing devices to compensate for w ear, and also for regulating the depth of the cuts.

A further object is to provide adjustable means for harrowing or spreading the strips or particles of clay thrown up by the plowing or scoring devices.

A further object is to simplify and cheapen thev construction disclosed in the patent above referred to and to adapt it for use as a unit and without change, on any and all makes of machines.

With these objects in view my invention consists in the parts and combinations of parts and in the details of construction as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in plan showing my improvement attached to the slicker or mouth piece of the 'die and showing the clay bar in its passage through the attachment; Fig. 2 is a view in slde elevation of the same; Fig. 3 is a view in vertical longitudinal section; Fig. 4 is a view in transverse section; Fig. 5 a view in section on the line :20 w of Fig. 4; Fig. 6 is a view of the frame and the harrow wires carried thereby and showing the relation of the latter to the clay bar, and Figs. 7, 8, 9, 10 and 11 are views of detached parts.

1 represents the slicker or mouth piece of a die, and 2 are plates bolted to the outer face of the slicker or mouth piece at opposite sides of, and in a plane above the die opening in the latter. Each plate 2 is provided with one or more bolt holes for the passage of the bolts 3, which secure the said plates to the die, and also with an offset portion 4 havingparallel elongated holes 5 for the attachment ofthe bracket 6, each of which latter consists of a vertical member 7 and two horizortalparallel members 8, all preferably cast integral. The upright member 7 of each bracket is provided adjacent its up per end, with the two elongated vertical slots 9 for bolts 10 which passing through the horizontal slots 5 in the plate 2 secure the brackets in position and permit them to be adjusted vertically and horizontally as may be necessary. There is one of these brackets at each side of the die opening, and

I the horizontal forwardly projecting members 8 of each, are provided with transverse elongated slots 11 (see Figs. 1, 4 and 5) in which the trunnions of the pressure rollers 12 are i mounted. These the trunnions of the rollers and at their other ends against screw- 14 by means of which the tension of the springs may be adjusted.

The upright portion of the brackets 6, intermediate the horizontal members 8 is provided with a series of transverse holes for the passage of the plowing pins 15, which are adjustably secured in place by the binding screws 16. Adjustably secured to and between the horizontal members 8 of the brackets 6 are the posts 17, one at each side of the machine. The posts are pivotally mounted on the screws 18, one at each end, so as to permit them to turn, and they are adjustably secured in position by the clamping screws 19, which pass through elongated slots 20 in the horizontal members 8 (see Fig. 1) and lock the posts in any position in which they may be placed within their limit of movement. Each post is provided with holes for the passage of plowin pins 21 which are adjustably secured in place by the binding screws 22. The pins 21 are arranged in horizontal planes between the pins 15 and as these pins of each set are comparatively close together, approximately the entire surfaces of the side edges of the clay bar'23,will be plowed or fur-rowed by the two sets of pins. The pins 15 are in rear of the rear pressure rollers 12, and the pins 21 are between the two rollers and are preferably disposed diagonally as shown so as to bring their cutting points close up to the rollers whereby the latter may catch and hold the strips or particles of clay displaced or thrown outwardly by the pins.

The plates 2 are also provided with bolt holes 22 for the attachment of the hinge members 24, each of which is provided with an elongated slot 25 for the passage of the securing bolt 26 whereby the hinge member 24 may be adjusted vertically. Pivotally secured to each hinge member 24, is alink 27 to the front ends of which the swinging bars 28 are hinged. These bars are rigidly connected by the rod 29, and by the pin or plow carrying plates 30 and 31, so that when the parts are assembled, the two bars 28 constitute a rigid frame which is free to rise and fall as will be hereinafter described.

The bar 30, as shown in Fig. 1, is provided at its ends with elongated slots 32, preferably open at the ends (as shown in Fig. 1) whereby it may be adjusted longitudinally or transversely of the clay ribbon or bar, and is held in place by"the bolts 33 passing through said slots and through holes in the horizontal flanges 28 of the swinging bars 28. It is also provided with a plurality of sets of holes, the holes of one set being intermediate the holes of. the next set for the passage of the scoring or plowing pins 34, which are adjustable and are held in place by the clamping screws 35.

The bar 31 is pivotally mounted at one end on the bolt 36 which is screwed into one flange 28 and is adjustably secured at its other end by clamping screw 37 passing through a hole in bar 31 and through an are shaped slot 38 in the flange 28 of the other swinging bar 28. By this construction, the bar can be swung on. its pivot 36 into an oblique position, and thus alter the relation of its pins 39 with the pins 34 of bar 30, so as to interfere with the scoring or furrows made by the latter and more completely obliterate them, thus producing the rough face and leaving but little if any of the evidence of the original scoring. The pins 39 in the bar 31 are staggered, as in bar 30, and are adjustably secured in place by the clamping screws 40.

Bolted to the swinging bars 28 are the uprights 41, connected at their upper ends by the box 41 which latter is designed to carry removable weights of any kind for holding the pressing rolls 42 down on the top face of the clay bar 23. Each upright 41 has an open slot 43 at the lower end for the bearings 44, in which the trunnions 45 of the presser roll 42 are mounted to move. These bearings 44 are connected with screws 46 having threaded engagement with the uprights whereby the bearings 44 may be adjusted so as to raise or lower the swinging or pivoted frame, which is composed of the swinging bar 28, cross bars 30 and 31 and the rod 29. The roller 42 rests on the top face of the clay bar and supports the free end of the pivoted frame and the adjustment of the roller 42 with relation to the said swinging frame controls the depth of cut of the pins or plows 34 and 39 after the latter have been adjusted.

Pivotally mounted on the rod 29 carried by the swinging bars 28, are the arms 49 to which the wire 50 is secured. This wire is secured at one end to one of said arms and at its other end to a hook screw 51, by means of which the tension on the wire may be regulated. The upper ends of each arm 49, is connected with an adjusting screw 52 (see Fig. 3) which passes through a hole in a bracket 53 rigidly secured to a swinging bar 28, so that by -means of the nuts 54 and 55 the arms 49 may be adjusted to carry the wire 50 toward or away from the clay bar so as to increase or lessen the interference of the wire with the plowed up surface of the bar as will be hereinafter explained.

Pivotally mounted on the horizontal bar 8 of the brackets 6 at each side of the swinging frame, are the horizontal arms 56 and 57, the arms 56 being pivotally mounted on the upper faces of the top bars 8 and the arms 57 pivotally mounted against the lower faces of the bottom bars 8, as clearly shown in Fig. 6. The arms 56 and 57 at each side of the apparatus, are connected by the tie rods 58, whereby the said arms at one side, are caused to move in unison, and each arm is connected with a screw by means of which the wire 60 carried by the said arms, may be moved toward or away from the sides of the clay bar 23. One end of each wire is secured directly to one arm, and the other end secured to the screw hooks 61 by which the tension of the wires may be regulated.

The depth of drop of the pivoted frame carrying the roller 42 and pin or plow bars 30 and 31, is controlled by the screws 62, (see Figs. 2 and 3).

The arrangement of the harrow wires 50 and 60 is shown in Fig. 6, and is such as to cause the wires to harrow the surfaces plowed up by the top and side plows or pins. These plowing pins are mounted so as to furrow the clay bar or ribbon on its top and two sides, and are quite numerous and so distributed as not to track one another. The pins are distributed over the entire area of the surfaces so that generally there is considerable space between two adjacent pins. The object of so locating them is to prevent the pins from tearing off large particles of clay, which might happen with certain clays if they were grouped close together.

The wires 50 and 60 are located in advance of the pins or are so located to act on the plowed surface of the clay bar or ribbon, after the latter has been scored, and operate to harrow or spread out and distribute the strips and particles of clay torn up by the pins or plows, in a confused or tangled layer evenly over the top and side surfaces of the clay bar or ribbon, and also disrupt and smooth down the edges and ridges of the furrows.

After the harrowing, the top face and sides of the ribbon are subjected to .the pressure of the rolls 12 and 42 which operate to compress and mat together the tangled strips and particles of clay, so that they will firmly adhere to the body of the ribbon thus producing the rough efiect with compara tively smooth or even surfaces.

Each pin or plow is adjustable so that the depth of furrow may be regulated, and by locating the plows which furrow the top faceof the clay ribbon or bar on the pivoted frame carrying the pressure roller 42, the

depth of cut will be regulated by the latter which is supported on and by the clay bar or ribbon, and hence causes the plows to maintain their parallelism with the face of the clay bar or ribbon. The furrow plowed up. should be comparatively deep and not mere scratches, so as to throw up ridges,

strips or particles of clay more or less detached from the body of the ribbon.

By providing the harrow wires, which as before explained, break down the ridges of the furrows and spread the strips and particles of clay in an even tangle over the top and end surfaces of the clay bar, with means for adjusting them toward and from the bar, the necessary changes for different depths of furrow can be accurately adjusted.

Immediately after the harrowing and before any loose particles can be dislodged and recedes from a swell in the clay bar, and by making the bars carrying the pins adjustable, the location of the latter can be changed to show or obliterate the scoring as may be desired.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but
